TECHNICAL FIELD

The technical field generally relates to a portable play structure for children, and more specifically to a portable climbing wall.

BACKGROUND

An important consideration for child development is play time that develops motor skills. Relating to play time, there are many play toys and structures targeted toward children. In particular, a climbing structure or a climbing wall may be an outdoor playing structure for children. Generally, the climbing wall is a permanently affixed structure at a park playground, school playground, etc. Children normally engage and play with the climbing wall by climbing up to a certain height with the assistance of hard points or permanently fixed or fastened handles placed on the climbing wall at different positions. Generally, these climbing wall structures are more of a permanent fixture and are bigger in dimension, non-collapsible, and non-portable. Playing outdoors is limited by the weather and playing on such structures may be hindered due to rain, snow, or extremely cold weather. Also, traveling to the playground where the structure is fixed is necessary, which may not always be feasible. Moreover, the climbing wall also requires a large area to buildup and is bulky in size. Hence, it makes the climbing wall difficult to move from place to place.

There are references that describe climbing structures for children. These references usually describe hard climbing surfaces that may have grips or integrated openings for climbing. The references also describe being able to adjust the angle of the incline. However, the references do not describe a structure that is designed with soft grips, padded surfaces or protective barriers for safety, portability, and adjustability in its features. Hence, there is a need for a small size, portable, collapsible, and easily configurable climbing wall that makes it is easier and safer for children to climb and improve their motor skills. There is also a need for a climbing wall that is designed for younger children, such as infants and toddlers. More specifically, there is a need for a climbing wall that can be easily assembled and disassembled into individual parts so that it is portable and reconfigurable at any place, either indoors or outdoors.

In the Summary above, in this Detailed Description, in the claims below, and in the accompanying drawings, reference is made to particular features (including method steps) of the invention. It is to be understood that the disclosure of the invention in this specification includes all possible combinations of such particular features. For example, where a particular feature is disclosed in the context of a particular aspect or embodiment of the invention, or a particular claim, that feature can also be used, to the extent possible, in combination with and/or in the context of other particular aspects and embodiments of the invention, and in the invention generally.

The term “comprises,” and grammatical equivalents thereof are used herein to mean that other components, ingredients, steps, among others, are optionally present. For example, an article “comprising” (or “which comprises”) components A, B, and C can consist of (i.e., contain only) components A, B, and C, or can contain not only components A, B, and C but also contain one or more other components.

The following description provides preferred exemplary embodiments only, and is not intended to limit the scope, applicability, or configuration of the invention. The following description of the preferred exemplary embodiment will provide those skilled in the art with an enabling description for implementing a preferred exemplary embodiment of the invention. It shall be understood that various changes may be made in the function and arrangement of elements without departing from the scope of the invention as set forth in the claims.

The present disclosure recognizes the unsolved need for a soft, foldable, adjustable, and portable climbing wall structure for children. Specifically, the invention relates to a foldable, indoor and outdoor climbing wall that is collapsible and configurable at the same time without the use of tools. The following description provides for a climbing wall that is configured to be easily carried and transported and thus allows it to be used anywhere. Additionally, the climbing wall is designed to be modular, safe for children to use, and comprised of materials that are environmentally safe.

The climbing structure is comprised of a frame, a padded layer, and a plurality of grips. The frame is comprised of at least two panels, a pair of side rails for each panel, a pair of adjustable bars, and a handle. The panels and the padded layer are provided with a plurality of openings which are designed to receive the detachable grips for climbing. A removable tube like padding also comprises part of the climbing structure and is configured to be placed over the side rails for protection.

The frame is comprised of at least two panels that are joined together to provide a stable surface for climbing. Each panel of the frame is preferably a flat, four-sided surface. The panels have a front surface, a back surface, a top side, a bottom side, a left side, and a right side. The top sides of the panels will be joined together. The front surfaces of the panels are the climbing sides of the climbing structure. The left side and right side are the vertical sides of the climbing structure. The panels may have a dimension including a height, width, and depth. Generally, the height will be more than the width and accommodate some climbing distance. In a preferred embodiment, the panels will be fashioned from a hard material which is light but can support the weight of a child. Materials that may be used include and are not limited to wood, plastic, composite, or a combination thereof. In alternate embodiments, the panels may be made of other material commonly used in this field, such as and not limited to metal.

As described above, the frame is comprised of at least two panels that are joined together at the top surface of each panel. Each panel has a hinge connected at the top surface. Other folding mechanisms and attachment systems known in the field are also contemplated to be used to connect the panels. In a preferred embodiment, the hinge is comprised of three circular features on each end of the top side of each panel. The top sides of each panel are aligned together with the hinge such that a quick release, removeable pin is then placed through the hinges at each end to securely adjoin the panels, requiring no tools to assemble or disassemble. Removing the quick release pin would disjoin and separate the two panels. Thus, the quick release pins make use of a method to give a locking action and are used for assembling and disassembling without using tools. A protective cover is placed over the gap created between the two panels when they are connected so as to prevent any injury with a body part getting caught in the gap.

In an alternate embodiment, the frame is comprised of at least three panels that are joined together to provide a stable surface for climbing. In this embodiment, a panel is provided that includes one or more hinges on the ends of the top side and the bottom side. This four hinged panel is adjoined to the remaining two panels that are described above. The four hinged panel is placed between these two panels and adjoined to those panels at their top sides by aligning the hinges and securing them together with the quick release pins. In this embodiment, the four hinged panel, or the middle panel, is arranged at the top when assembled and is parallel to the ground that the climbing structure is placed on. Thus, a child would climb up one panel which is at an incline to get to the top panel, which is a flat surface parallel to the ground, and then climb down the opposite panel, which is also at an incline.

The frame is also comprised of a side rail. Each panel of the frame is configured with at least two side rails along the vertical sides, with one side rail on each of the left side and the right side. The side rails provide a form of protective barrier around the vertical sides of the frame. In a preferred embodiment, the side rails and panels are dove tailed together and secured together with screws or similar fasteners. In an alternate embodiment, the panels are configured with the side rails, such that the side rails are a permanent feature of the panels. The side rails are fashioned of the same hard material as the panels which include and are not limited to wood, plastic, composite, or a combination. In alternate embodiments, the panels may be made of other material commonly used in this field, such as and not limited to metal.

The frame is also comprised of the pair of adjustable bars. The adjustable bars are designed to attach to the side rails configured on the panels. The side rails are either configured with one hole or a plurality of pass-through holes that are aligned vertically in a straight line and include at least two pass-through holes. Each panel of the frame is configured with each type of side rail such that one vertical side is configured with the side rail with one hole and the other vertical side is configured with the side rail with the plurality of pass-through holes. In the preferred embodiment, the side with the plurality of pass-through holes includes four pass-through holes. The panels are configured with the side rails such that the hole and pass-through holes configuration will always be the same. For example, the panel pieces will be configured with the side rails including the plurality of pass-through holes on the left sides and the therefore the side rails with the one hole will be on the right sides, or vice versa. Thus, when the panel pieces are adjoined together at the top end with the hinge and the pin, the side rails of the adjoined panels will line up with the one hole and the pass through holes on the same side such that the pair of adjustable bars can be connected to the side rails, with one on each side.

As disclosed above, the side rails are configured to be connected to the adjustable bar. The adjustable bars allow the angle of incline to be adjusted and securely lock it in position. The adjustable bar is an elongated piece with two ends, a pivoting end and an adjustable end. The pivoting end of the adjustable bar is secured to the side rail that contains a single hole. The pivoting end is aligned with the one single hole on the side rail and secured to the side rail with securing means such as and not limited to a screw. The adjustable end of the adjustable bar includes a thumbscrew and is connected to the side rail having the plurality of pass-through holes; the adjustable bar connects to one of the pass-through holes and is securely locked with the thumbscrew at a chosen angle. The adjustable end thereby allows the adjustable bar to attach to the side rail and lock the climbing structure at a specific angle.

In the preferred embodiment, the adjustable bar can be attached and locked into four different angles. As such, the choices for the specific angles include, but are not limited to, a 120 degree angle, a 90 degree angle, a 60 degree angle, and a closed position of zero degrees.

The frame also comprises the handle. The handle is configured near the bottom end of the panel. In this embodiment, the handle is configured as an opening in the panel such that a person may place a hand through the handle to carry the climbing structure. In other embodiments, the handle can be connected to the panel rather than being built into the panel.

The climbing structure also comprises the padded layer. The padded layer overlays and covers the front surface of the panels of the frame. In a non-limiting preferred embodiment, the padded layer is permanently attached to the panels. In other non-limiting embodiments, the padded layer is attached non-permanently to the panels with means that allow the padded layer to be attached and removed from the panels, such as, but not limited to, Velcro® and snap and button fasteners. In a non-limiting preferred embodiment, the padded layer is made from Ethylene-vinyl acetate (EVA) to give the padded layer a soft and padded feel. The EVA padded layer is arranged into a flat layer and is laid over the front surfaces of the panels to provide a soft climbing surface. In other non-limiting embodiments, the padded layer is made with a stuffing material with an outer layer that encloses the stuffing. In this embodiment, the stuffing layer and the outer layer are also arranged into a flat layer so that the padded layer can be laid over the front surfaces of the panels. Stuffing material may include organic, synthetic, or eco-friendly stuffing. Organic and or eco-friendly stuffing material may be derived from and not be limited to corn, bamboo, cotton, wool, and kapok. Synthetic stuffing material may be derived from and not limited to polyester and toy stuffing pellets.

In the non-limiting preferred embodiment, the panels comprising the frame include a plurality of openings over the front surface which extend through the back surface. The padded layer also includes a plurality of openings such that the openings in the padded layer align with the openings in the frame, wherein the openings are open from the padded layer to the front surface of the panel and through the back surface of the panel. In other non-limiting embodiments, the plurality of openings over the front surface of the panels do not go through the back surface (i.e. do not open at the back surface), such that the openings go from the padded layer through the front surface of the panel without an opening in the back surface. In yet another embodiment, the openings are only included in the padded layer with no openings in the panels. The plurality of openings are evenly interspersed on the panels and the padded layer. In other non-limiting embodiments, the openings are scattered throughout the panels and padded layer in a non-even manner such that the plurality of openings are not in a line.

In the preferred embodiment, the plurality of openings in the panels have a clover shape. As discussed below, the clover shape allows the grip to be inserted in four different orientations. In other non-limiting embodiments, the plurality of openings can be in other shapes such as and not limited to a circle/slot, a circle, an oval, a square, a rectangle, a triangle, and a polygon (i.e heptagon, hexagon, etc.).

The plurality of openings are designed to allow grips to be inserted into them. The grips are interspersed throughout the panels and allow the child to climb the climbing structure using the hands and feet. The grips are comprised of a foam portion and a base. The base is designed such that a portion of the base is securely fastened to the panel. In the preferred embodiment, the grip portion is fashioned out of material that is soft such as, but not limited to, EVA foam. The grip portion can also be fashioned by other non-toxic material known in the art. In the preferred embodiment, the grip portion is designed in a shape resembling the number eight (8). This allows two different orientations of the grip portion for use in climbing: a vertical orientation or a horizontal orientation. In other non-limiting embodiments, the grip portion is designed with other shapes that have a cross section including and not limited to a circle, an oval, a square, a rectangle, a triangle, and a polygon (i.e. heptagon, hexagon, etc.). In yet other non-limiting embodiments, the grip portion can also include animal shapes.

The base is coupled to the grip portion and is generally designed to conform to the shape of the plurality of openings in the panels. In the preferred embodiment, the base will have a portion that has a clover shape such that it fits within the clover shape of the plurality of openings in the frame (discussed above). The clover shape base portion prevents spinning of the grip and essentially allows the grip to be placed into an opening in one of four different orientations. In the preferred embodiment, the base includes a threaded portion that is designed to extend out from the back surface of the frame such that a fastener can be screwed onto the base and securely hold the grip in place. The fastener may include and not be limited to a collar or similar fastener. The threaded portion of the base also serves a safety purpose wherein the threaded portion is color coated. When a colored threaded portion of the base extends past the fastener (when screwed onto the threaded portion on the back surface of the panel), it visually signals that the grip is properly secured to the panel and safe to use.

The base and the fastener are fashioned from material that is strong and can withstand the weight of a child. Materials include, but are not limited to, plastic, wood, metal, composite, or a combination thereof.

In the preferred embodiment, the placement of the grips is adjustable. In this embodiment, the grips can be inserted in any opening in the padded layer of the panels. The grips can be removed and moved to other openings on the padded layer and panels. The grips can be placed in all the openings or can be inserted in only a few openings to offer variety and challenge. The climbing structure is also comprised of plugs that can be placed over the openings on the padded layer which do not receive the grips.

Alternate embodiments of grips are also described and comprise part of the climbing structure. One embodiment is comprised of a grip portion which is coupled to a base that has a hollow threaded portion which a fastener with a threaded portion can be inserted into. In this embodiment, the base is inserted through an opening in the panel wherein the grip portion rests against the padded layer on the front side of the panel and the fastener with the threaded portion is inserted into the hollow threaded portion of the base to secure the grip onto the panel.

Another alternate embodiment of a grip is comprised of a grip portion which is coupled to a base which has an opening designed to accommodate a screw. The grip is also comprised of a fastener with a corresponding opening designed to accommodate the screw. In this embodiment, the base is inserted through an opening in the panel wherein the grip portion rests against the padded layer on the front side of the panel, the fastener is fit against the base on the back side of the panel, and the screw is inserted through the fastener and the base to secure the grip.

Another alternate embodiment of a grip is comprised of a grip portion which is coupled to a base which has a recessed portion designed to accept a clip. In this embodiment, the base is inserted through the opening in the panel wherein the grip portion rests against the padded layer on the front side of the panel and the recessed portion on the base exits through and is exposed on the back side of the panel. The clip is inserted onto this recessed portion on the backside of the panel to secure the grip onto the panel. The clips can include, but are not limited to, a spring clip, a cotter pin, or any other pins or clips that are known to be capable of being used in this type of design.

Another alternate embodiment of a grip is comprised of a grip portion which is coupled to a base which has an opening to accommodate a screw. The grip is also comprised of a fastener which has a thumb screw design with a screw portion. In this embodiment, the base is inserted through an opening in the panel wherein the grip portion rests against the padded layer on the front side of the panel and the screw portion on the fastener is screwed onto the base on the back side of the panel to secure the grip to the panel.

Another alternate embodiment of a grip is comprised of a grip portion which is coupled to a base having snap hooks. The base is designed with snap hooks such that the base is inserted through an opening in the panel and the snap hooks rest against the back side of the panel to securely hold the grip to the panel.

The climbing structure will also be comprised of accessories that can be attached to the climbing structure. The accessory can include the additional panel (disclosed earlier) which can be attached at the top end in between the two panels used at an angle of incline. Another accessory includes a sliding surface that can be attached to one side of the frame. Attachment means may include, but not be limited to, a hook at a top end of the slide that can be slid over the top end of one of the panels of the frame.

An exemplary configuration of a climbing structure is shown in the accompanying figures. With reference to FIG. 1, a non-limiting preferred embodiment 100 of a climbing structure is shown. In this preferred embodiment, a climbing structure is generally comprised of a frame, wherein the frame is comprised of at least two panels 102, a pair of side rails 104 for each panel 102, and a pair of adjustable bars 106 connected to the side rails 104 on each of a side of the panels 102. FIG. 1 further illustrates a plurality of grips 120 and an overlaid padded layer 110 that overlays the panels 102 of the frame. An elongated padded layer in a shape of a tube is also provided to cover each side rail 104, referred to as a padded tube 130. The climbing structure also comprises a handle 140.

As shown in FIG. 1 and FIG. 2, the frame of the climbing structure 100 is comprised of at least two panels 102 that are joined together at a top end of each panel 102. Preferably, the panels 102 are hingedly connected. As illustrated in the close-up view of the connection in FIG. 3, each panel 102 has a hinge 150 connected at the top end. The hinge 150 is comprised of three circular features on each end of the top side of each panel 102. The top sides of each panel 102 are aligned together with the hinge 150 and a pin, such as a quick release pin 152, is then placed through the hinges 150 at each end to securely adjoin the panels 102, requiring no tools to assemble or disassemble. The quick release pin 152 can be removed to disjoin and separate the two panels 102. Additionally, a protective cover preferably is placed over the gap created between the two panels when they are connected (not shown).

Referring to FIG. 1 and FIG. 2, the frame of the climbing structure 100 is also comprised of the side rail 104. Each panel 102 of the frame is configured with at least two side rails 104, with each side rail 104 positioned on a vertical side of the panel 102. Accordingly, a left side and a right side of a panel 102 contains a side rail 104. The side rails 104 provide a form of protective barrier around the vertical sides comprising the frame. The side rails 104 and panels 102 can be attached to each other. For example, the side rails 104 and panels 102 can be dove tailed and secured together with screws or alternatively, the panels 104 can be permanently attached to the side rails 102. The elongated padded tube 130 is provided to be placed over the side rails 104 to add a padded protection.

The side rails 104 are also configured to connect to the adjustable bars 106. As illustrated in the close-up view in FIG. 2, the side rails 104 are either configured with one hole 154 or a plurality of pass-through holes 156 that are aligned vertically in a straight line. In FIG. 2, four pass-through holes 156 are shown. Each panel 102 of the frame preferably is configured with each type of side rail 104 such that one vertical side is configured with the side rail 104 with one hole 154 and the other vertical side is configured with the side rail 104 with the plurality of pass-through holes 156.

The panels 102 are configured with the side rails 104 such that the configuration of the single hole 154 and pass-through holes 156 will always be the same. For example, the panels 102 will be configured with the side rails 104 including the plurality of pass-through holes 156 on the left sides of the panels, and therefore the side rails 104 with the one hole 154 will be on the right sides of the panels, or vice versa. Accordingly, each panel 102 will have the same side rail 104 configuration as the other panel 102. Thus, referring back to FIG. 2, when the panels 102 are adjoined together at the top end, the side rails 104 of the adjoined panels 102 will line up such that the one hole 154 and the pass through holes 156 are on the same side of the structure 100, which allows the pair of adjustable bars 106 to be connected to the side rails 104, with one on each side of the adjoined panels 102.

The adjustable bars 106 are connected to the side rails 104 on the panels 102. The adjustable bar 106 is an elongated piece with two ends, a pivoting end 162 and an adjustable end 164. The pivoting end 162 of the adjustable bar 106 is aligned with and secured to the side rail 104 at the single/one hole 154. The pivoting end 162 and the side rail 104 are secured together with securing means that permit the pivoting end 162 to pivot, such as, but not limited to, a screw 166. The adjustable end 164 includes a thumbscrew 168 and is connected to the side rail 104 (having the plurality of pass-through holes 156) at one of the pass-through holes and is securely locked in place using the thumbscrew 168.

The adjustable end 164 can be secured at any one of the pass-through holes 156 which allows the adjustable bar 106 to attach to and lock the climbing structure 100 at a desired angle. FIG. 5A through FIG. 5D illustrate specific angles that the climbing structure 100 can be adjusted to. As shown, the adjustable bar 106 can be attached and locked into any one of four different angles. FIG. 5A shows the climbing structure 100 at a 120 degree angle; FIG. 5B shows the climbing structure 100 at a 90 degree angle; FIG. 5C shows the climbing structure 100 at a 60 degree angle, and; FIG. 5D shows the climbing structure 100 in a closed position. In the closed position, the climbing structure 100 can be carried and stored easily, such as in a trunk of a car, thereby making it portable.

The frame also comprises the handle 140. As shown in FIG. 1, the handle 140 is configured near the bottom end of the panel 102. In this embodiment, the handle 140 is configured as an opening in the panel 102 such that a person may place a hand through the handle 140 to carry the climbing structure 100. In other embodiments, the handle can be connected to the panel rather than being built into the panel.

Referring back to FIG. 1, the climbing structure 100 is also comprised of the padded layer 110. The padded layer 110 is overlays and covers the front surfaces of the panels 102 of the frame. In a non-limiting preferred embodiment, the padded layer 110 is permanently attached to the front surfaces of the panels 102. In other non-limiting embodiments, the padded layer 110 is attached non-permanently to the panels 102 with means that allow the padded layer 110 to be attached and removed from the panels 102. The padded layer 110 is arranged into a flat layer and is laid over the front surfaces of the panels 102 to provide a soft climbing surface.

As shown in FIGS. 1 and 2, the panels 102 of the frame include a plurality of openings, referred to as panel openings 103, over the front surface of the panel 102 and which extend through the back surface. The padded layer 110 also includes a plurality of openings, referred to as padded layer openings 113, such that the padded layer openings 113 align with the panel openings 103. The panel openings 103 and padded openings 113, are aligned together and interspersed throughout the panels 102 and the padded layer 110. The panel openings 103 and the padded layer openings 113 are designed to accommodate and allow grips 120 to be inserted into them.

Referring to FIGS. 4A through 4C, a preferred embodiment is shown illustrating the panel openings 103, the grip 120, and the grip inserted into the panel 102 with the padded layer 110, respectively. FIG. 4A shows a close-up view of a section of the front surface of the panel 102 without the padding layer to illustrate the panel openings 103. In this preferred embodiment, the panel openings 103 are shown to have a clover shape. In this embodiment, the clover shape allows the grip 120 to be inserted in four different orientations.

Referring to FIG. 4B, an exemplary embodiment of the grip 120 is illustrated, whereby the grip comprises a grip portion 122, a base 124, and a fastener 126. The base 124 is coupled to the grip portion 122 and is generally designed to conform to the shape of the panel openings 103 in the panels 102 of the frame. In the preferred embodiment, the base 124 is designed with a portion that has a clover shape, such that it fits within the clover shape of the panel openings 103 in the panels 102. FIG. 4C illustrates an inserted grip 120, wherein the base 124 is inserted into the padded layer 110 and extends through the panel 102 and is secured at the back surface of the panel 102 with the fastener 126. The grip portion 122 rests against the front surface of the panel 102 with the padded layer 110. The clover shape portion of the base 124 prevents spinning and essentially allows the grip 120 to be placed in the panel openings 103 in any one of four orientations. For example, the figure eight shaped grip 120 (as shown in the FIGS. 1-3, 4B, and 6) can be oriented with the eight in a vertical position or alternatively it can be placed with the figure eight in a horizontal position.
